A liver function test measures ALT, AST, ALP and GGT, which are enzymes that rise when liver or bile duct cells are under strain, with bilirubin and albumin. At The Wellness in Marylebone it costs £350, as the Core Wellness panel, with results in 24 to 48 hours and a doctor to explain the result.
A liver function test measures ALT, AST, ALP and GGT, which are enzymes that rise when liver or bile duct cells are under strain, with bilirubin and albumin.
Together they suggest whether the liver is inflamed, whether bile is flowing freely, and how well the liver is making protein.
A doctor may ask for it if you drink more than the recommended limit, carry weight around the middle, take medicines that affect the liver, or have symptoms such as yellowing of the skin or dark urine.
Fatty liver often shows first as a raised ALT in someone who feels well.
No fasting is needed. Avoid heavy exercise and alcohol for a day before if you can, because both can raise the enzymes for a short time.
It does not always. Scarring can be present with normal enzymes, which is why a doctor may add a scan or a fibrosis score when the history suggests it.
Usually a repeat test, a look at alcohol, weight and medicines, and often an ultrasound of the liver.
Choose a panel and a time for the draw in clinic. A doctor reads the result before it reaches you, and rings or writes with what it means and what to do next. Or ring 020 3951 3429.
